VEDET-500TZN Colorimetric Heavy Metal Water Quality Online Analyzer
Product Description
VEDet-500 TZn colorimetric heavy metal water quality online analyzer using high sensitivity analysis. In the high temperature closed conditions, the use of persulfate in water samples of zinc compounds into zinc ions, in alkaline medium, zinc ions and zinc reagent to form a strong absorption in the characteristic wavelength of the compound. The TZn content in the water sample was calculated by measuring the compound.
VEDet-500 TZn colorimetric heavy metal water quality online analyzer is widely used in industrial production processes (electroplating, chemical, rare earth and other industries) in the total zinc monitoring occasions.
Product Features
High reliability, low maintenance
The key components are imported parts, high reliability, long life, suitable for long-term on-line monitoring;
Metering module using photoelectric measurement method, the detector is not in direct contact with the liquid, does not appear irresolute situation.
Flow through a special design, not easy to plug.
Mature technical means to ensure high accuracy
Photoelectric measurement using a special measurement algorithm, making the injection is accurate, small sample error.Unique bubble mixing technology to ensure that the continuous injection, the sample and reagent fully mixed. Automatic chroma, turbidity compensation algorithm, taking full account of the actual situation of water samples, the monitoring results are true and reliable.
Patented circular multi-channel dilution sampling technology to achieve a large range of ratio expansion.
A variety of practical functions, to provide user-friendly operation.
Automatic leakage alarm function, when a reagent leak, the instrument self-test alarm, prompting the user for maintenance.
Abnormal state of automatic processing, when the operation occurred during the abnormal power-down until the next restoration of power supply, the instrument will self-diagnosis of abnormal state, and restore the flow channel to wait for the state to do the sample.
Instrument operation is simple, full touch screen control panel and friendly software interface, providing a wealth of information tips, software, easy to understand With multi-level management authority to set the password and the screen digital lock, to prevent misuse of others.
